Definitions

  • the invention relates to a blower, in particular for hair dryers, with a cup-shaped housing cap arranged on the blower housing and reaching over the suction opening and which has a plurality of slits for concentrating circular lines and radial lines of an annular surface in the edge region for the passage of suction air, the latter each with in extending axial slots are connected to the circumferential surface of the housing cap.
  • this object has found a solution in that the central axes of the slots formed in the edge region of the housing cap are inclined with respect to the radial lines against the direction of rotation of the blower and form an acute angle with the radial lines.
  • a hole pattern with a large opening ratio for the intake air flow is achieved in the housing cap bottom, which additionally results in a flow-guiding effect for increasing the air throughput.
  • the blower is characterized by a large air throughput with little noise.
  • the central axes of the slots form a straight line. It is also possible to design the central axes of the slits as curved lines. The curvature of the curved lines can be chosen arbitrarily. Finally, it is provided to form the slits in a top view of the cap base with central axes inclined to the left or right.
  • 1 denotes a blower for hair drying, the housing 2 of which accommodates an electric motor, a blower wheel and an electric heating register (not shown) in a manner known per se.
  • the electric motor and the heating register can be applied to a power source in a further known manner by means of switching elements.
  • 3 with a handle is designated, which is hinged to the housing 2.
  • the blower air can be fed to the blower via a blower housing cap 4 with air passage openings 5 and exits freely through an exhaust air opening in the blower housing 2.
  • a number of slits formed in the form of ring sections on concentric circular lines of the blower cap base 4 'and additional slits 6 in the edge region thereof are provided.
  • the slits 6 are oriented in their inclination from the outside inwards with respect to radial lines 7 against the direction of rotation of the blower and form acute angles ⁇ with the radial lines 7.
  • the slots 6 continue in the housing cap circumferential surface in axial slots 8. It has been found that the inclination of the slits 6 in connection with the axial slits 8 results in a substantial increase in the air throughput at the same speed of the fan blade. It is in accordance with the essence of the invention that the slots 6 can either be designed with straight central axes (FIG. 2) or, as shown in FIGS. 3 and 4, with curved central axes. The inclination of the slots 6 in the cap base 4 'can run to the left or right. The direction of rotation of the fan blade (not shown) is opposite in each case to achieve the most favorable air throughput.
